Abstract
|
|
|
|
The concentration of total phenolic compounds of the water and ethanol extracts of Yerusalem sage were 9.4mg/g and 11.1mg/g respectively. The total antioxidant activities of water and ethanol extracts of Yerusalem sage were 96.8% and 91.4% in ABTS assay and 97.6% and 87.2% in DPPH assay, PF of the water and ethanolic extracts were 1.1 and 1.6, respectively. TBARS were 0.9×10?3 μM and 0.3 ×10?3 μM, respectively. Antimicrobial effect against H. pylori of the ethanol extract was 9~15 mm of clear zone diameter at 50 μg/ml~200 μg/ml of phenolic compound. Phenolic profiles in Yerusalem sage chlorogenic aicd was the highest both in water and ethanol extracts in HPLC analyses.
